Yes, Jodi's posts are very insightful, and there is where I discovered Dr. de Wit and his "Aniseikonia Inspector" software. However, finding a doctor near me who is willing to learn to make use of it and a lab that is capable of making bi-toric lenses are my present challenges.
Use the search feature and archives and search "aneisokonia" and read the many posts especially those by JodiJ who has written many detailed posts about her own experience with the problem
